This subsequent review was actually based on 2 Oppo player level mod from us. The first part of the review is based on our Premium mod for digital section on Oppo 105D (Linear Power Supplies, and Low jitter clock for digital section only). It does not contains any direct mods to the analog section to the Oppo (for the RCA and XLR output). Even so the improvement to the digital and analog output of the player is substantial.
